Hi Bill, Sure. Love to carry on about it. Virtual Box was always open sourced, to an extent. VBox 4.x is slower than 3.2.12. I can not take any more performance hits. I am still on 3.2.12 for the same reason you are using old-out-of-date Enterprise Linux. I also almost got fired over Virtual Box and still may. Fortunately, as a private contractor, I do not have all my eggs in one basket. A collection of some of my "recent" bug reports. http://www.virtualbox.org/ticket/7628 http://www.virtualbox.org/ticket/7643 http://www.virtualbox.org/ticket/7607 http://www.virtualbox.org/ticket/7948 http://www.virtualbox.org/ticket/7957 http://www.virtualbox.org/ticket/7772 And, the one I almost got and still may get fired over: http://www.virtualbox.org/ticket/8478 8478 corrupted the hell out of a Visual Fox Pro and and M$SQL 2008 database. And you *can not* purchase a support contract with Oracle for Virtual Box. I wasted about 10 hours trying. I have completely lost confidence in Oracle. Red Hat, on the other hand, I love. I snooped on the KVM developers list and Holy Cow! are they ever developing like crazy. I no longer want to trust a Virtual Machine where the developers have to be pushed kicking and screaming into fixing anything. HTH, -T Anyone have a chance to look over my qemu-ing run string?
